Answer 1

Answer:

$29.25

Step-by-step explanation:

Divide the cost of the turkey by 12 to obtain the unit cost then multiply this by 13

cost = $\frac{27}{12}$ × 13 = $29.25

Answer 2

Answer:

$29.25

Step-by-step explanation:

In order to calcualt ethe cost of a 13 pound turkey knowing that the cost of turkey is proportional and we know that a 12 pound turkey costs $27, we can just make a rule of three to calculate the 13 pound turkey, like this:

$\frac{12}{27}=\frac{13}{x}$

Now we clear the x on the function to be able to calculate the cost:

$x=\frac{(27)(13)}{12}$

$x=29.25$

With this we know that the cost of a 13 pound turkey would be $29.25
